Abstract
The utility model relates to a kind of soil column sampler, including drill bit, the inner hollow of drill bit is embedded in earth pillar container in drill bit internal, and the open end of drill bit is equipped with cutter head, and the tail portion of drill bit connects sampler.The sampler combines operation mode of drilling, and is transformed to drill bit, earth pillar container is embedded into drill bit, and the acquisition of soil sample is completed while being drilled.It has the advantage that soil sample original state property conservation degree is higher compared with traditional approach, influence of the surrounding soil to cylinder soil can be simplified；Dramatically simplify sampling step, the investment to use manpower and material resources sparingly；Sampling operation can be carried out in complicated landform, it is not necessary to use a large amount of tools.
Description
Technical field
The utility model relates to the soil column leaching of radionuclide migration characteristic research field, especially a kind of soil column
Sampler.
Background technique
In radionuclide migration characteristic research, indoor soil-column experiment always is its most important research means.Soil
Column experiments can be divided into disturbance soil column leaching and soil column experiment by whether the soil body occurs disturbance, wherein due to soil column reality
Test can natural reality reflect practical field soil mass property and by the favor of various countries researcher.Soil column experiment is maximum tired
Difficulty is the acquisition of soil column, and how to complete the acquisition of cylinder in minimal disturbances is urgent problem.
Excavation is mostly used to fill out the mode of column for the acquisition of shallow-layer undisturbed soil sample at present, i.e., cutting out sampled point surrounding soil makes
Soil sample protrusion, after earth pillar container is inserted into earth pillar, following problems will be generated using the method: (1) during cutting out surrounding soil
The sampling soil body will be affected greatly, or even there is a situation where " soil mass fragmentations "；(2) soil sample protrusion part will be with earth pillar container
It matches, it is excessively slightly meticulous all to have an immense impact on to soil sample, but be often difficult to reach this requirement under actual conditions.For deep layer
Soil sample acquisition, generally requires to carry out exploratory trench sampling i.e. by exploratory trench operation, depth up to requiring depth, after earth pillar container is carved into
Side wall is sampled, and the method will expend a large amount of manpower and material resources, and be difficult in complicated landform.Therefore, it is badly in need of one
Kind can save trouble and labor and reach it is accurate and keep soil sample original state property sampling tool or method.
Utility model content
Purpose of the utility model is to solve defects of the existing technology, provide a kind of soil column sampler.
To achieve the goals above, the technical solution adopted in the utility model is:
A kind of soil column sampler, including cylinder, the inner hollow of cylinder are internally embedded earth pillar container in cylinder,
One end of cylinder connects cutter head, and the other end of cylinder is drilling machine connector, and drilling machine connector is connect with drilling machine machine bar.
Further, the earth pillar container is in hollow cylindric and both ends open.
Further, the cutter head is in frustoconical, the inner hollow of cutter head and both ends with opening, the tail portion opening of cutter head
It is connected with the open-ended of earth pillar container.
Further, the inner wall of the cutter head is arcwall face.
Further, the end thread of the cutter head and cylinder connects, and drilling machine connector is threadedly coupled with drilling machine machine bar.
Further, the material of the cylinder is steel, and earth pillar container is machine glass column.
The utility model has the following beneficial effects: the sampler combines operation mode of drilling, drill bit is transformed, by earth pillar
Container is embedded into cylinder, and the end of cylinder has the cutter head connect fastly, and the acquisition of soil sample is completed while being drilled.With biography
System mode can simplify influence of the surrounding soil to cylinder soil compared to having the advantage that soil sample original state property conservation degree is higher；
Dramatically simplify sampling step, the investment to use manpower and material resources sparingly；Sampling operation can be carried out in complicated landform, it is not necessary to use
A large amount of tools.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the schematic cross-section of the utility model.
Specific embodiment
As shown in Fig.1 and Fig.2, a kind of soil column sampler, including cylinder 1, the inner hollow of cylinder 1, in cylinder 1
It is internally embedded earth pillar container 2, one end of cylinder 1 connects cutter head 3, and the other end of cylinder 1 is drilling machine connector 4, drilling machine connector 4
It is connect with drilling machine machine bar.
Further, the earth pillar container 2 is in hollow cylindric and both ends open, and cutter head 3 is in frustoconical, cutter head 3
Inner hollow and both ends have opening, and the tail portion opening of cutter head 3 is connected with the open-ended of earth pillar container 2, and the inner wall of cutter head 3 is
Arcwall face.
Further, cutter head 3 is connect with the end thread of cylinder 1, and drilling machine connector 4 is threadedly coupled with drilling machine machine bar, cylinder 1
Material be steel, earth pillar container 2 be machine glass column.
The sampler combines operation mode of drilling, and is transformed, earth pillar container 2 is embedded into cylinder 1, cylinder to drill bit
1 end has the cutter head 3 connect fastly, and the acquisition of soil sample is completed while being drilled.Have compared with traditional approach following
Advantage: soil sample original state property conservation degree is higher, can simplify influence of the surrounding soil to cylinder soil；Dramatically simplify sampling
Step, the investment to use manpower and material resources sparingly；Sampling operation can be carried out in complicated landform, it is not necessary to use a large amount of tools.
Basic principles, main features, and advantages of the present invention has been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only the principles of the present invention, the utility model also has respectively on the premise of not departing from the spirit and scope of the utility model
